| v.build.all | v.build.all |
| v.build | Crea la topologia per i dati vettoriali GRASS. |
| v.build.polylines | Costruisce poligoni da linee. |
| v.category | Attach, delete or report vector categories to map geometry. |
| v.clean | Toolset to clean vector topology. |
| v.convert.all | |
| v.convert | Importa vecchie versioni dei vettori di GRASS. |
| v.db.connect | prints/sets DB connection for a vector map |

| v.delaunay | Create a Delaunay triangulation from an input vector of points or centroids. |
| v.digit | |
| v.distance | Find the nearest element in vector 'to' for elements in vector 'from'. Various information about this relation may be uploaded to the attribute table of input vector 'from' or printed to stdout. |
| v.external | Create a new vector as a read-only link to OGR layer. Available drivers: |
| v.extract | Selects vector objects from an existing vector map and creates a new map containing only the selected objects. If 'list', 'file' and 'where' options are not specified, all features of given type and layer are extracted, categories are not changed in that case. |
| v.hull | Uses a GRASS vector points map to produce a convex hull vector map |
| v.in.ascii | Convert GRASS ascii file or points file to binary vector. |
| v.in.db | Create new vector (points) from database table containing coordinates. |
| v.in.e00 | Importa file E00 in una mappa vettoriale. |
| v.info | Outputs basic information about a user-specified vector map layer. |
| v.in.garmin | Upload Waypoints, Routes, e Tracks da un Garmin GPS ricevendoli in una mappa vettoriale. |
| v.in.ogr | Converte vettori OGR in vettori GRASS. Driver disponibili: |
| v.in.region | Crea un nuovo vettore dalla regione corrente. |
| v.in.sites.all | |
| v.in.sites | Converts a GRASS site_lists file into a vector file. |
| v.kcv | Randomly partition points into test/train sets. |
| v.kernel | Generates a raster density map from vector points data using a moving 2D isotropic Gaussian kernel or optionally generates a vector density map on vector network with a 1D kernel |
| v.label | Create paint labels for GRASS vector file and attached attributes. |
| v.mkgrid | Creates a (binary) GRASS vector map of a user-defined grid. |
| v.neighbors | Makes each cell value a function of the attribute values assigned to the vector points or centroids around it, and stores new cell values in an output raster map layer. |
| v.net.alloc | Allocate subnets for nearest centres (direction from centre). Centre node must be opened (costs >= 0). Costs of centre node are used in calculation |
| v.net | Network maintenance. |
| v.net.iso | Split net to bands between cost isolines (direction from centre). Centre node must be opened (costs >= 0). Costs of centre node are used in calculation |
| v.net.path | Find shortest path on vector network. Reads start/end pointsfrom standard input in 2 possible formats: |
| v.net.salesman | Create a cycle connecting given nodes (Traveling salesman problem). Note that TSP is NP-hard, heuristic algorithm is used by this module and created cycle may be sub optimal. |
| v.net.steiner | Create Steiner tree for the network and given terminals. Note that 'Minimum Steiner Tree' problem is NP-hard and heuristic algorithm is used in this module so the the result may be sub optimal. |
| v.normal | tests for normality for points. |
| v.out.ascii | Convert a GRASS binary vector map to a GRASS ASCII vector map |
| v.out.dxf | Esporta un file vettoriale di GRASS in un file di fomato DXF. |
| v.out.ogr | Convert to OGR format. |
| v.out.pov | Convert to POV-Ray format, GRASS x,y,z -> POV-Ray x,z,y |
| v.overlay | Overlay di due mappe vettoriali. |
| v.patch | Creates a new binary vector map layer by combining other binary vector map layers. |
| v.perturb | Random location perturbations of GRASS sites. |
| v.proj | Allows projection conversion of vector files. |
| v.qcount | indices for quadrat counts of sites lists |
| v.random | Randomly generate a GRASS vector points map. |
| v.reclass | Changes vector category values for an existing vector map according to results of SQL queries or a value in attribute table column. |
| v.sample | Sample a raster file at site locations. |
| v.segment | Create points/segments from input lines, and positions read from stdin in format: |
| v.select | Select features from ainput by features from binput. |
| v.surf.idw | Surface interpolation from sites data by Inverse Distance Squared Weighting. |
| v.surf.rst | Interpolation and topographic analysis from given point or contour data in vector format to GRASS floating point raster format using regularized spline with tension. |
| v.to.db | Load values from vector to database. In uploaded/printed category values '-1' is used for 'no category' and 'null'/'-' if category cannot be found or multiple categories were found. |
| v.to.points | Create points along input lines. |
| v.to.rast | Converts a binary GRASS vector map layer into a GRASS raster map layer. |
| v.transform | Transforms an vector map layer from one coordinate system into another coordinate system. |
| v.type | Change the type of geometry elements. |
| v.univar | Calculates univariate statistics for attribute. Variance and standard deviation is calculated only for points. |
